The classical approach of avoiding or ignoring interference in wireless networks cannot accommodate the ambitious quality-of-service demands of ultra-dense cellular networks (CNs). However, recent ground-breaking information-theoretic advances changed our perception of interference from a foe to a friend. This paper aims to shed light on harnessing the benefits of integrating modern interference management (IM) schemes into future CNs. To this end, we envision a hybrid multiple access (HMA) scheme that decomposes the network into sub-topologies of potential IM schemes for more efficient utilization of network resources. Preliminary results show that HMA can multiply non-orthogonal multiple access performance, especially under dense user deployment.
